What is the Shielding Approach?
The shielding approach aims to reduce the number of severe COVID-19 cases by limiting contact between individuals at higher risk of developing severe disease (“high-risk”) and the general population (“low-risk”). High-risk individuals would be temporarily relocated to safe or “green zones” established at the household, neighborhood, camp/sector or community level depending on the context and setting. They would have minimal contact with family members and other low-risk residents.

No surprises that we have two such quarantine prisons pop up in Auckland. But then we are DS bought and paid for. Ozzie are still building theirs.
